【摘要】 目的 :提高对迟发性对冲性颅内损伤的进一步认识。材料与方法 :搜集复查时发现迟发性对冲部位颅内新病变和 /或病变增大者 31例 ,分析其CT表现。结果 :首次检查发现 :脑挫裂伤 12例、SAH16例、SDH8例、EDH4例 ,复查出现 ;脑内血肿 2 2例 (其中 10例为原挫裂伤部位出现血肿 )、脑挫裂伤 9例、EDH 6例。结论 :脑对冲伤后可出现多种情况的迟发性对冲性颅内损伤 ,其发生率较高 ,应注意复查CT ,尤其是首次检查出现脑挫裂伤或SAH者 ,更是复查对象。伤后 3天内CT复查至关重要。更多还原

【Abstract】 Purpose:To intensify the cognition of delayed contra-coup cerebral injury.Materials and Methods:31 cases with newly-appeared lesions and/or enlarged lesions in the opposite areas,when taken CT re-examination,were retrospectively analysed.Results:On the first CT scan,12 cases with cerebral contusion and/or laceration,16 cases with Subarachnoid hemorrhage(SAH),8 cases with Subdural hematoma(SDH) and 4 cases with Epidural hematoma(EDH) were found.on CT re-examination scan,22 cases with intracranial hematoma,9 cases with cerebral contusion and/or laceration,and 6 cases with EDH were discovered.Conclusion:Delayed contra-coup cerebral injury varies on CT scan,and it has a higher incidence,It’s necessary to take CT re-examination,especially for the patients with cerebral contusion and/or laceration,or SAH on first CT scan,The appropriate CT re-examination time is in three days after tranma.更多还原
